JAMES P. COLLINS, OF TROY, NEW YORK.

HANGER FOR SHAFTING.

Specification of Letters Patent No. 30,206, dated October 2, 1860.

To all whom it may concern:

Be it known that 1, JAMES P. COLLINS, of Troy in the county of Rensselaer and State of New York, have invented a new and Improved Hanger or Suspended Bearing for Shafting; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a vertical section of my in vention, taken in the line .22, a, Fig. 2. Fig. 2 is a vertical section taken in the line 3 Fig. 1. Fig. 3 is a detached view of the bearing and cup.

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to obtain a bearing of simple construction which will have a universal adjusting movement, and at the same time be properly supported at all points so as to admit of belts being applied to the shafting in any direction.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents a cast iron pendent frame, secured in the usual manner to the liooring beams or ceiling of the building where the shafting is to be hung. This frame A may be of any suitable shape, that shown in Fig. would probably be as desirable as any. At the inner side of the frame A, at two opposite points there are shoulders at, a, which form supports for a curved plate B, the latter being secured on the shoulders by bolts Z). Through the center of the plate B, an arbor or rod C, passes vertically, and through the center of the bot-tom of the frame A, a screw 0, passes vertically, the latter serving as a support for the arbor (Z, of a cup or shell D, which is placed within the frame A.

The cup or shell D, may be of cast-iron of oblong form, as shown in Figs. 1 and 3, the arbor (Z, projecting down from the center of the bottom of the cup or shell, and fitting within a recess 6, at the bottom of the frame A, the screw 0, extending up within said recess, as shown in Figs. 1 and 2. At one side of the cup or shell D, there is a curved -arm E, which extends over the top of the cup or shell 2. trifle beyond its center and through which the rod 0, passes. The rod C, it will be seen, and the arbor (Z, form the axis of the cup or shell D, the latter being allowed to turn or work horizontally on said axis. On the cup or shell D, there are two bearings f, 7. These bearings are placed at opposite sides of the cup or shell and receive the trunnions g, g, of a box or hearing F, the trunnions being allowed to work freely in the bearings hrough each side of the cup or shell a screw h, passes, and these screws form stops for the ends of the trunnions g, and admit of a lateral adjustment of the latter in the bearings f, f, as shown clearly in Fig. 2.

G is the cap or top of the box or bearing F, on which the end of the rod O, bears, the upper part of the top G, being rounded'so as to form a segment of a cylinder, the trunnions being at the center thereof. Into the upper part of the plate B, a screw 2', passes to secure the rod C, at any desired point.

From the above description it will be seen that the box or bearing F, has a universal adjusting movement and that it may be readily made to conform to the line of the shafting, the cup or shell D, which catches the waste lubricating material, admitting of a horizontal turning movement, the screw c, effecting a vertical adjusting movement of the box or bearing separately and the trunnions g, admitting of a turning movement of the box or bearing in a vertical plane. At the same time it will be seen that the box or bearing F, is supported at all sides the rod C, serving as an upper stay, and the screws lb, h, as lateral ones. Belts therefore may be run from the shafting in any direction and the latter be perfectly supported.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the shaft box F, trunnions g, and adjusting screws h, of the shell D, arm E, rod G, curved plate B, arbor (Z, screw 0, and frame A, in the manner and for the purpose herein shown and described.

2. The peculiar arrangement of the cap G, with the trunnions and the rod (l, as and for the purpose herein shown and described.
